of Seljuk, who with his tribe crossed from Turkestan
into Transoxiana and embraced Islam with deep fervour.
He and his descendants took part in the wars of the
period, and speedily came into collision with Mahmud.
The story runs that the great Conqueror asked Israil, the
son of Seljuk, how many men followed him to battle, to
which the nomad chief replied that if he despatched an
arrow to his tents one hundred thousand men would
prepare for war, but that if his bow were seen two
hundred thousand men would join the former force.
Sultan Mahmud, alarmed at this new power, imprisoned

moving it away from its habitat, settled it in the district
of Nisa,1 and in Abivard, near the modern Kakha on the
Central Asian Railway. The newcomers, under their
chief, Mikail, proved unruly, and in the year before the

Khwarazm both seized the opportunity to throw off their
allegiance. But Masud was no weakling, and in A.H. 426
(1035) he brought a large army from India, drove the
Ghuzz from Tus and Nishapur, and invaded Tabaristan,
which submitted. He then left Khorasan and busied
himself with his possessions in India, to which he attached
greater importance, probably because they yielded a larger

against the Ghuzz and who aided him in driving these
